COOLER Original Filed Jan. 14, 1929 Patented Dec. 8, 1931 UNITED STATES PATENT OFFICE PBILIP S. CAMPBELL, OF HOU'STON, TEXAS,ASSIGNOR OF ONE-HALF T O MARCHI CULMORE, O]? HARRIS COUNTY, TEXAS COOLER Application filed January 14, 1929, Serial No. 332,512. Renewed October 12, 1931.

This invention relates to new and useful improvements in a cooler.

One object of the invention is to provide a cooler particularly designed for cooling water and other liquide and embodying a liquid container, an ice compartment a'ssociated therewith and a pasSageway leading from said compart-ment to the atmosphere and which is surrounded by the liquid to be cooled.

While the utensil is particularly useful for cooling liquids it is capable for use for coolin purposes generally.

th the alcove and other objects in v1ew this invention has particular relation to certain novel features of construction, arrangement of parte and use, an example of which is given in this specification and illustrated in the accompanying drawings wherein gure 1 showsa pian view of the cooler, an

Figure 2 shows a vertical sectional view thereof. V

Referring now more particularly to the drawings, wherein like numerals of reference designate similar parte in each of the figures the numeral 1 designates a suitable container having a bottom 2 and anupstanding, upwardly tapering tube 3 secured to said bottom, providing a chamber 4 to contain the liquid or articles to be Cooled.

Detachably secured to the lower end'of the container 1 there is a cup-like refrigerant receptacle 5 which may be screwed onto the lower end of said container 1.

This receptacle is provided to contain a refrigerant, such as ordinary ice, or solid carbon dioxide, as desired. If so1id carbon dioxide is used the receptacle walls should be double and spaced apart, as shown in Figure 2, to provide a space 6 between said walls. This construction Wil1 prevent the ice from melting too rapidly and will prevent the utensil fro1n becoming frozen to the support on which it is located.

As the ice melts the air in the refrigerant receptacle 5 and the tube 3 Will expand and gradually pass out to the free atr'nosphere and the utensil will thus be protected from bursting by reason of such expansion. The liquid in the chamber 4: in contact with the bottom '2 and tube 3 Will also be kept very cool.

VVhat I claim is 1. A device of the character described including a container open at the top and baving a tube therein, a refrigerant compartment adjacent said container into which the tube is connected said tube extending through the container from bottom to top and being open at -one end to the atmosphere.

2. A device of the character described including a container, an acljacent refrigerant compartment formed With double walis spaced apart, and a tube leading from said cornpartment through said container and open to the atmosphere at its free end, the wals of said tube converging to said free en 3. A device of the character described. including a container, refrigerant compartment below said container and a tube leading from said compartment and arranged in said container and its walls converging to a free end provided with a restricted opening to the atmosphere.

4:. A cooler for liquids and the like including a container open at the top, an upwardly tapering tube in, and secured to the bottom of the container, and whose upper end has an outlet opening in substantially the same plane as the piane of said top, a refrigerant receptacle secured to the bottom of the container with which ,said tube communicates.

In testimony wherof I have signed my name to this specification.

PHILIP S. CAMPBELL.
